FIELD: electricity.
SUBSTANCE: method comprises forming an electric arc between the welding electrode and the welding structure periodically short-circuited by drops of melted from the electrode. Each cycle consists of a welding arc short-circuit period, in which an electrode is fed with high-current pulse, and the arc period, in which the electrode is fed with a high current pulse, which is followed by a low current pulse. In each welding cycle embedded energy during short-circuit is determined and set of the embedded energy of EHD in the arcing period, proper condition of ≥ EHD.
EFFECT: improving of the quality of the weld formation.
